APPARATUS FOR BURNING KEROSENE-OIL FOR FUEL.

SPECIFICATION forming part of Letters Patent No. 397,150, dated. February 5, 1889.

Application filed February 29, 1888. Serial No. 265,764. (No modcld To aZZ whom, it may concern:

Be it known that I, GREENLEAF Ii. SWETT, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Burning Kerosene-Oil for Fuel, of which the following is a specification.

My invention relates to devices to be used to contain the kerosene-oil to be used as fuel, and for controlling and bringing it to the point of combustion, the object being to provide a simple and practical device for burning kerosene in cooking or heating stoves.

This-improved apparatus comprises an oiltank, a mass of asbestus or other incombustible fiber, (which I term the mass-wick,) par tially filling said tank, and a porousblock fitted within said tank and covering the masswick, said block being provided with wickholes, through which individual wicks extend through the porous block to the mass-wick beneath the block.

The porous block may be composed of lireclay and sand, mixed, worked, molded, and burned, after the manner in which fire-bricks are made, the wickholes therein being formed in any suitable manner. This brick is adapted to fit within the tank, and when placed therein rests upon and completely covers the top area of the mass-wick and fills the tank to a line within about one-sixteenth of an inch of its top. The porous block serves as a cover for holding the fiber of the mass-wick in position, as a wick for absorbing and conducting the oil to its upper surface by capillary attraction, and as a wick-holder for the individual wicks.

The individual wicks may be composed of twists or braids of asbestus, and are placedin the wick-holes in the porous block before the latter is adjusted in the tank.

In the use of my improvement the tank is filled with kerosene or equivalent hydrocarbon until the latter shows on the top side of the porous block. A lighted match is then applied to one of theindividual or point wicks,

and the oil on the entire upper surface of the porous block will become ignited and will continue to burn with intensity for an hour, more or less, according to the size of the tank.

In the drawings annexed, Figure 1 is aperspective view of this improved apparatus for burning hydrocarbon oil. Fig. 2 is a longitudinal section thereof. Fig. 3 is a perspective view of the porous block constituting a part thereof.

(1 marks the wall of the tank.

a marks the porous block.

a marks the pointrwicks and the vertical apertures through the porous block.

(0 marks a bail to handle the tank by.

I claim as my invention- The combination of the containing-tank a, the mass wick a therein, the porous block a, covering the top of the mass-wick, said porous block being provided with wick-holes, and individual wicks a, extending through said block onto the mass-wick, substantially as described.
